Problems solved by technology

[0017] The positive electrode non-coating region 115 disposed on both surfaces of the positive electrode current collector 111 and the negative electrode non-coating region 125 disposed on both surfaces of the negative electrode current collector 121 lead to electrode failure due to not forming an active material layer in the entire space. The capacity of the assembly 100 is reduced
